Total mileage for this outing was 20.7 miles of which 6.0 miles was by mountain bike. Fairly long day for me. I confined 14.5 mile portion of hike I did on foot to this map view. it shows locations of former RR bridges, and most importantly Thoreau Falls Bridge. I did a 1/2 mile side trip to site of an old RR bridge that used to cross the Pemi just below junction of North and East Branch. I did a 3.0 side trip up to Camp 24 to look at the artifacts to be found there. It is against the law to remove artifacts from WMNF.
